Disrupted Event Processing for All Customers
Resolved - This incident has been resolved. Affected unsubscribe events have been replayed. And as noted before, inbound subscriptions during the incident period can not be replayed.
Apr 24, 19:13 EDT
Monitoring - We have observed recovery of affected systems.

We are in the process of replaying affected unsubscribe events, and other remaining queued events have been processed. Event processing, API responses, and latency are all up-to-date. Unfortunately, inbound subscriptions during the affected period can not be replayed.

We will provide another update once unsubscribe events have been replayed.
Apr 23, 18:01 EDT
Identified - We have addressed the underlying issue. We are seeing improvement in event processing, API responses and latency, email sending, and other areas.

We are continuing to work on fully restoring normal operations.
Apr 23, 15:41 EDT
Investigating - We are experiencing disruption in event processing since 2pm EST. Customers may see high error rates with APIs, missing metrics, and delayed sending.

We are investigating the issue and working to mitigate it currently.

Delays in Email Sending
Resolved - We can confirm that all delayed emails have caught up as of approximately 7:15 PM US Eastern, and email sending is back to real time.
Apr 23, 19:53 EDT
Investigating - Beginning around 5 PM US Eastern time, we began observing delays in email messages sent by a mail delivery partner. In addition to a subset of campaign and flow messages, this may affect emails for multi-factor authentication login and double opt-in emails.

Mail is being accepted and processed, but is delayed; we do not expect data loss. We will provide further updates as we have them.
